This filter transforms the image with the Mandelbrot fractal: it maps the image to the fractal.
You get to this filter via the Image menu through
→ →Mandelbrot parameters
These parameters are similar to X/YMIN, X/YMAX and ITER parameters of the Fractal Explorer filter. They allow you to vary fractal spreading and detail depth.
Mapping image to fractal may reveal empty areas. You can select to fill them with Black, White, Transparency or make what disappears on one side reappear on the opposite side with Wrap option.
